How to Fix No Sound or Speaker Not Working on Xiaomi Phone

Fix xiaomi speaker not working and redmi no sound. Solve poco audio fix for xiaomi speaker muffled with hyperos sound issue.

No sound from your Xiaomi phone's speakers can have several causes — most of them fixable in minutes. Work through these steps in order.

Step 1: Check Volume and Silent Mode

Press the Volume Up button to raise media volume. Make sure the phone is not in:

• Silent Mode (check the notification shade or side button)
• Do Not Disturb (DND) mode — go to Settings > Sound > Do Not Disturb and disable it

Step 2: Check for Bluetooth Audio Conflict

If sound is playing through a Bluetooth device you're not using, your phone's speaker will be silent. Go to Settings > Bluetooth and disconnect any connected devices.

Step 3: Check If Headphone Mode Is Stuck

Plug in and unplug headphones to reset the audio jack detection. If the phone "thinks" headphones are plugged in, it won't play audio from the speaker. Try blowing air into the headphone jack or USB-C port.

Step 4: Clean the Speaker Grille

Dirt and lint in the speaker grille can muffle or block sound completely. Use a dry, soft brush to gently clean the bottom speaker grille.

Step 5: Run the Speaker Hardware Test

Dial *#*#64663#*#* in the Phone app → select Speaker from the test menu. This plays test tones through each speaker independently to identify hardware failure.

Step 6: Restart and Check Sound

A simple restart often resolves audio routing bugs in HyperOS.

Step 7: Check App Audio Settings

Some apps (music, video) have their own volume controls separate from the system. Ensure volume within the specific app isn't muted.

Step 8: Factory Reset / Service Center

If hardware test shows speaker failure, visit a Xiaomi service center. Speaker replacement typically costs $20–$50.
